Tuna, Bluefin (Hon Maguro)

Bluefin Tuna is the largest tuna species and one of the largest fish in our oceans, growing to 1543 pounds and over 13 feet in length.

Bluefin tuna is caught in the Pacific, Atlantic, Southern Oceans and Mediterranean and are severely depleted worldwide. All populations are being caught at rates faster than they can reproduce.

Fishers use surface gears, typically rod and reel, longlines and purse-seines to target this highly valuable species. When caught with longlines, there is bycatch of threatened and endangered species, like sea turtles, sharks, and seabirds.
